An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-8311 in the wild and no public exploit code.\n\nAffected product: Microsoft Lync. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2018-8311/ (Markdown: https://insights.sbomify.com/CVE-2018-8311/index.md)","id":"CVE-2018-8311","markdown":"https://insights.sbomify.com/CVE-2018-8311/index.md","name":"CVE-2018-8311","record":{"aliases":["GHSA-v5v7-qp5p-hxjg"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Skype for Business","requires_auth":"none","summary":"Attackers can execute arbitrary code remotely by sending specially crafted content to Skype for Business or Lync clients.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"lync","vendor":"microsoft"},{"product":"skype_for_business","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A remote code execution vulnerability exists when Skype for Business and Microsoft Lync clients fail to properly sanitize specially crafted content, aka \"Remote Code Execution Vulnerability in Skype For Business and Lync.\" This affects Skype, Microsoft Lync.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Code injection in Microsoft Lync","id":"CVE-2018-8311","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2018"},"n_packages":0,"n_references":4,"next":{"headline":"Memory corruption in Microsoft Access","id":"CVE-2018-8312"},"packages":[],"prev":{"headline":"Other in Microsoft Office","id":"CVE-2018-8310"},"products":["Microsoft Lync","Skype"],"published":"2018-07-11","related":[{"cvss_score":9.8,"headline":"Microsoft Office Elevation of Privilege Vulnerability","id":"CVE-2020-1025","kev_date_added":null,"published":"2020-07-14"},{"cvss_score":9.3,"headline":"Use after free in n/a","id":"CVE-2013-1302","kev_date_added":null,"published":"2013-05-15"},{"cvss_score":9.3,"headline":"Path traversal in n/a","id":"CVE-2012-1849","kev_date_added":null,"published":"2012-06-12"},{"cvss_score":8.8,"headline":"Auth bypass in Skype for Business","id":"CVE-2017-11786","kev_date_added":null,"published":"2017-10-13"},{"cvss_score":8.8,"headline":"Memory corruption in Uniscribe","id":"CVE-2017-0283","kev_date_added":null,"published":"2017-06-15"},{"cvss_score":8.8,"headline":"Memory corruption in Graphics","id":"CVE-2017-8527","kev_date_added":null,"published":"2017-06-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Microsoft"]},"summary":"Attackers can execute arbitrary code remotely by sending specially crafted content to Skype for Business or Lync clients.","url":"https://insights.sbomify.com/CVE-2018-8311/"}
